Settable surgical implants and their packaging
The present invention relates to settable compositions for use in surgery. The invention also provides related compositions, including surgical kits and packages, as well as methods of making and using the settable compositions.
Fracture fixation systems
Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.

Biocomposite for regeneration of injured tissue and organs, a kit for making the biocomposite, a method of making the biocomposite and a method of treating injuries
Provided is a biocomposite including cells, a genetic construction, and a scaffold and a method for repairing tissue and organs in mammalians with the biocomposite. The interaction of the components of the biocomposite provides a complex effect on reparative regeneration processes. Also provided is a method for administration of gene-cellular therapeutic constructions to a recipient which can be used in medicine and veterinary to provide reparative processes. After administering the biocomposite to a recipient, the scaffold structure releases the nucleic acids which enter into the cells of a recipient bed and cells of the transplanted product. The nucleic acids are expressed, which results in the increased concentration of a target product responsible for reparative processes.

Implantable medical device with varied composition and porosity, and method for forming same
A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.

Fabrication of bone regeneration scaffolds and bone filler material using a perfusion flow system
The present disclosure is directed at a process to form bone grafting material. One may provide a porous collagen scaffold and insert the scaffold into a perfusion chamber of a perfusion flow system. This may then be followed by continuously providing a mineralization perfusion fluid flow through the scaffold at a flow rate to provide dynamic intrafibrillar mineralization of the scaffold and form a collagen/hydroxyapatite composite scaffold. One may optionally provide the scaffold with bone tissue forming cells and then deliver a perfusion fluid including oxygen and one or more nutrients through the collagen/hydroxyapatite composite scaffold and to the bone tissue forming cells at a flow rate such that the bone tissue forming cells remodel the collagen/hydroxyapatite composite scaffold and form a bone tissue extracellular matrix. The bone tissue extracellular matrix may then be decellularized to form an acellular bone repair scaffold.
